To all whom t may concern' Be it hown that l, JAMES ld. SrANonnn, a citizen of the United States, residing at Canton, in the county of Stark and State of hio, have invented a new and use Suction @arpet-Sweeper, or which the following is a specication.

This invention relates to improvements in carpet sweepers provided with means for producing a suction or strong inrush of air into the. device, which inrush of air operates in conjunction with the brush for the purpose of brushing and pneumatically cleaning doors and door coveringand similar surfaces.

The objects of this invention are to gen erally improve devices of the character described and to provide a construction which will be composed of few and simple parts puttogether in a practical manner, the various parts being so exactly and peculiarly adapted to each other that the combine to produce a substantial and e cient carpet sweeper. One of the important 'objects of the present invention is to provide improved means to actuate a brush by the traveling wheels upon which the sweeper is mounted. Another object is to provide improved means whereby sucient fractional contact between the traveling wheels and the brush is maintained of sucient degree under all circumstances to insure the proper rotation of the brush durin the time the sweeper is moved back and orth upon the surface to be cleaned.

l'lhese objects, to apparent to those s obtained by the construction the accompanying drawings, although the invention may be embodied 1n other forms, the construction illustrated being chosen by wa of example..

it Fi ether with other objects illed in the art, may be illustrated in the accompanying drawing: 'gure 1 ie a perspective view showing all of the parts proper y arranged with reference to each other.

Fig. 2 is an end view oi the brush casin with the removable closing plate detache also showing one of the traveling wheels in proper relative position with reference to the brush.

ln the accompanying drawing, l represents the combined brush. casing and motor support, which is substantially of' the torna shown in Fig. 1 and as shown it is so constructed that a motor can be attached and connected to a suitable suction fan. To the casing or frame l is also pivotaily attached the yoke 2, to which yoke is attached the handle 3. 'lhese parts so far as the motor, yoke and handle are concerned are shown conventionally and do not form any specidc part of the present invention, except that such parte are necessary in the construction of a complete suction carpet sweeper oiz the style and kind to which the present invention belon s.

lo the rame l are attached the supporting wheels 4, which supporting wheels are so adjusted with reference to the brush casing and frame that the underside or the bottom or the brush casing and frame will be held a short distance above the surface or' the floor, carpet or rug upon which the traveling wheels are brought in contact. For the purpose of properly connecting the traveling wheel l to the frame l the bolts 5 are provided, which bolts pass through suitable flanged thimbles (i and the rearward extended flanges 7, which rearward extended flanges are preferably formed integral with the combined brush casing and traine l..

li: desired the traveling wheels d may be directly mounted upon' the bushings or thimbles 8, which thimbles may be iormed of fibrous material, but this is a question of judgment, but il believe is the preferable way to mount the traveling wheels. iin use it may be desirable to adjust the traveling wheels 4, vertically with reiierence to the This adjustment can be roviding the elongated slots 9, through w ich elongated slots the bolts 5 are passed. Within the brush casing. is located the brush ill, which brush is of the brought about .by

usual construction such as commonly used in sweepers of the class to which this invention belongs. The endsof the brush are provided with the spindles 11, which spindles are referably, securely connected to the brush ody and are formed of a suiicient length to 'be carried by the bearings 12, which bearings are carried by the fixed and detachable endA plates 13 and 14, both of said plates being provided with the elongated slots 15 and i6.,A

he purpose of detachably connecting one brush casing is to parts, more especially the brush and its various parts, and also for removing and relacv ing the brush from time to time or tuting new brushes for worn ones.

The traveling Wheels 4f are provided with which. tires are preferably formed of rubber or like material for two purposes, first, to prevent the traveling Wheels from slipping upon the floor or sursu stiface, and second, to insure the proper rotation of the brush by means of the rubber or like rings 18 fixed to the ends ot the brush. In order that the rings 18 may be brought snugly against the rubber or like tires 17 upon the travelin wheels 4f, the brush bearings 12 are slida ly mounted in the elongated slots 15 and 16, said bearings being provided with the fiat faced bosses 19 located in the slots 15 and 16 and the springs 2O connected to the bearings 12 and to the brush casing, said springs being so tensioned that they will lnormally press the bearings 12 toward the traveling wheels 4f, thereby insuring the proper andsuiiicient frictional contact between the rings 18 and the tire 17 to at all times and under all ordinary circumstances rotate the brush during the time the sweeper proper is moved back and forth upon the :door or other surface..

In order to bring the traveling wheels d and the rings 18 into' proper alineinent with lframe and brush incense reference to each other, the brush casing" a5 1s formed ot such a length that the rings 18 can be located within' the brush Casin and the traveling wheels outside ofthe brush casing. This arrangement being best illustrated in Fig. 6, and also illustrated in Fig. 2. lt will be understood that the springs 20 should be rovided with suitable attaching tangs 21, wiiich tangs may be located through suitable apertures 22 or theirequivalents.

It will be understood that by providing the springs 2O and locating the same as shown, therings 18 will be forced against the eripheries or tires ot the traveling whee s et. lhe pressure being ot such a degree that under ordinary circumstances there can be no slipping las between the brush driving rings and the traveling wheels.

Having fully described my invention what claim as new and desire to secure by Letters Patent, is-

In a suction carpet sweeper of the class described, the combination of a combined casing, the ends of the brush casing extended beyond the ends of the frame, traveling wheels rotatably mounted upon and adapted to support the frame, a brush located within the brush casing, said brush being adapted to be rotated by the rotation of the travelin wheels, the bearings of said brush being sliably mounted in the end plates ol thebrush casing, and springs connected to the bearings and tothe brush casing, said springs vadapted to normally press the brush bearings toward the traveling wheels.

In testimony that Si claim the above, l have hereunto subscribed my name in the presence of two witnesses.
